The application of space technology and the challenges of managing water infrastructure in a selected South African municipality
(2023-04) Mokgobu, Matlou Lesley; Mason, Roger Bruce
The installation of water infrastructure in cities poses a challenge to communities, municipalities, and installation contractors. These challenges range from the inaccessibility of streets, the community’s limited access to homes, traffic jams, deep trenches with few or no barricades, leaking water pipes, water supply cut-offs, electricity supply cut-offs, vandalism, and theft of water pipes and accessories. The research problem, therefore, revolves around a better understanding of these water infrastructural problems, how to mitigate such problems caused by inadequate planning, leading, organising, controlling, and coordination by management, arising from various technical aspects of water infrastructure. The need for this study arises from the inconvenience and dangers experienced by communities with heaps of materials lying around causing disturbances to traffic flow, open hazardous trenches becoming dangerous to children playing in their vicinity, vehicle accidents because of the trenches, and damaged kerbs. The study aimed to investigate the challenges of managing water infrastructure in a selected South African municipality to find possible ways to resolve such challenges with the help of space technology. The study achieved the objectives, namely, to identify the challenges experienced by the municipality during and after the installation of water infrastructure; to rank the importance of the experienced challenges; to explore the root causes of the challenges experienced during the installation of water infrastructure; to identify how space technology can help with the management of water infrastructure; to develop a framework of the challenges and the causes; and, to explore water management strategies with the effort of finding possible ways to resolve the challenges. The study was exploratory and applied mixed methods research methodology. Data was collected via a survey (402 City of Tshwane residents), in-depth interviews (20 City of Tshwane managers of the Water Division), and two focus groups (7 participants per group of City of Tshwane contractor managers and contractor employees) through the convergent parallel design method. The quantitative data was analysed using the Statistical Package for Social Sciences (SPSS Version 27), and the qualitative data was analysed using NVivo version 27, charts, tables, and themes. The results from the three sets of participants indicated multiple challenges related to skills deficits, management deficits, political interference, and inexperienced staff in the water infrastructure division. The findings indicated knowledge, ability and performance gaps in human resources, management, technical skills, financial management, socio-politics, and legal frameworks. The study contributed new knowledge to systems theory regarding the policies, systems, installation and maintenance of water infrastructure, and communication, and these aspects are supported by the findings. The application of space technology on a large scale can help the City of Tshwane fight criminal acts of vandalism and theft of infrastructure. This study found that space technology is still in its infancy in the city, and that the application of this technology requires an elevated level of education, experience and specialised technical skills to operate. This study recommended extensive investment in space technology. The study further recommended that the City of Tshwane improve human resources, training, culture, finance, operations, and control measures. The study recommended further research on the proper use of funds, the causes of community violence against the contractors doing maintenance, investigation of the delays in the procurement of services, turnaround time for the various water infrastructure activities, relationship management between the city employees and the contractors, the impact of lack of reporting by the managers and employees to the superiors in the water infrastructure division, and clearer definition of roles between municipal employees and politicians. More academic research into water infrastructure, based on the use of and relationship between water infrastructure and space technology, is warranted.
Challenges during installation and maintenance of water delivery infrastructure : a citizen perspective
(Beykent University, 2023-10-30) Mokgobu, Matlou Lesley; Mason, Roger; Dobbelstein, Thomas
The installation and maintenance of water infrastructure in South African cities poses a challenge to communities, municipalities, and installation contractors, who face problems such as inadequate access to homes, traffic jams, inadequately barricaded trenches, leaking water pipes, water supply cut offs, vandalism, and theft of water. The research problem, therefore, involves an inadequate understanding of what drives these problems and how to mitigate them through better management. The aim of this study was to investigate the challenges of managing water infrastructure as perceived by the citizens of a South African municipality. The study was a descriptive and cross-sectional survey, with data collected, via a literature derived, emailed questionnaire, from a self-selected non probability sample of 402 City of Tshwane residents. Analysis, via SPSS Version 27, used descriptive and inferential statistics. The findings revealed that both the municipality and the contractors contributed to the challenges experienced by citizens, with maintenance challenges being more serious than installation challenges. Municipal and political challenges were the main drivers, with political ownership of construction companies and political interference being the biggest problems. The findings contributed to a better understanding of the challenges inhibiting effective installation and maintenance of water infrastructure, and are important to the municipality, and the community at large, because they contribute to a better understanding of service delivery from the citizens’ perspectives.
Potential of space science technology for water infrastructure management : a literature review
(Center for Strategic Studies in Business and Finance SSBFNET, 2022-03-16) Mokgobu, Matlou Lesley; Mason, Roger Bruce
This article examines the potential of space science technology for water infrastructure (WI) management. It defines space technology in detail, and when South Africa (SA) started using it as a tool. To explain the context, the different types of orbits, altitudes, and functions of satellites are given, as well as the challenges that satellites encounter in orbit, including the quantity and sizes of orbital debris also known as space junk. The article articulates the international and local challenges to WI and further introduces space technology as a tool that can assist to overcome the challenges. Legislation governing the application of space technology in SA is discussed and the different satellites owned by the various space agencies of Africa are outlined. A discussion on how space technology has boosted the economies and employment in Africa and South Africa is provided. How the various applications of the technology, such as remote sensing (RS), Earth observation (Eo), Geo-Information sciences, navigation, communication, safety, and security can assist WI management are discussed. Details about the involvement of various African and SA universities and colleges in space science programmes that benefit the communities are explained. Also outlined are some experiments performed on the International Space Station (ISS) that benefit the Earth and that could be useful to WI management.
